Thomas Malthus:
Thomas Malthus' Theory of Population that was proposed more than two centuries ago, foretold the problems of food shortage that the world is facing today, due to uncontrolled increase in population.
Thomas Robert Malthus was a British economist and a demographer, whose famous Theory of Population highlighted the potential dangers of overpopulation. Malthus put forth his ideas in six editions of his famous treatise 'An Essay on the Principle of Population'. His thinking took shape under the influence of the optimistic ideas of his father and his friends especially Rousseau, for future improvement of the society. In the first edition of his treatise, Malthus put forth his views that opposed the belief of scholars like Marquis de Condorcet and William Godwin who were optimistic about population growth in England. During the Industrial Revolution, England experienced a steep increase in its population. In his book "The Enquirer", William Godwin promoted population growth as a means for human beings to attain equality. According to him, an increased population would create more wealth that would provide food for the whole humanity. Scholars of such school of thought believed that, both man and society could be made perfect. In contrast to this viewpoint, Malthus interpreted overpopulation as an evil that would reduce the amount of food available per person.
The Theory:
In his famous treatise 'An Essay on the Principles of Population', Malthus stated that, the populations of the world would increase in geometric proportions while the food resources available for them would increase only in arithmetic proportions.
In simple words, if human population was allowed to increase in an uncontrolled way, then the number of people would increase at a faster rate than the food supply. A point would come when human population would reach the limit up to which food sources could not support it. Any further increase
